Abstract

La réduction du bruit dans des images multi-spectrales numérisée est obtenue par le filtrage fondé sur des valeurs vectorielles plutôt que sur des valeurs scalaires indépendantes. Des valeurs vectorielles vers un pixel avec au moins deux valeurs. Dans ce procédé, une mesure est définie pour la longueur du vecteur de pixel. Un noyau de traitement glissant est également défini avec une format spécifié, un nombre de pixels spécifié à inclure dans ce noyau et un seuil de contraste de valeurs spécifié de façon à éviter des bords de distorsion et des détails fins. La mesure et le noyau sont utilisés pour sélectionner des pixels en vue d'un filtrage par calcul du pixel central dans un noyau. Une mesure statistique est calculée, par exemple par la moyenne des pixels spécifiés et, la valeur résultante est considérée comme la valeur du pixel central de ce noyau. Ce processus de filtrage est appliqué à travers l'image, chaque pixel étant considéré au centre d'un noyau de traitement.
